How to Play Major & Minor Related Keys in Jazz Guitar

Video Transcript

" Hi! My name is John Armstrong with expertvillage.com. I am a professional guitar instructor and today we are going to be studying beginning jazz guitar. What the concept of related keys can do for you is a few things. First off, it tells you that the notes in those 2 related scales are exactly the same. For example, here is a Major scale; G, A, B, C, D, E, F sharp G. Here's an E minor scale; E, F sharp G, A, B, C, D and E. The same notes but arranged in a different order. The major scale starts and ends on a G note, the E natural minor scale. Since the notes are the same, the chords are going to come out the same. The key of G major has a G major 7, A minor 7, B minor 7, C major 7, B7, E minor 7, F sharp minor 7 flat 5 and G major 7. With the key of E minor is going to be the same but it is going to start in a E minor chord. That is going to be my tonic chord, the E minor chord. Keep this in mind, this is only through the E natural minor scale or the natural minor scale. Later we will discuss the harmonically minor scales. Here my tonic chord E minor 7, F sharp minor 7 flat 5 for my 2 chord, G major 7 for my 3, A minor 7, B minor 7, C major 7, D7 and back to E minor 7. So the chords are the same. I have the same 7 chords names and chord qualities but the difference is the that the song of the key of G major wants to resolve or come to rest at the G major 7 chord or the G major chord and the song of the key of E minor will want to come to rest at the E minor chord.
